I sympathize with this as a pragmatic solution to the lack of resolution
on negotiating content quality, an old HTTP idea that has never quite

However, I would hate to see Accept: not defined in so far as client
helpers are defined. Many potential applications of helpers are crippled
currently because the client does not send the browser a list of the types
accepted by its associated helpers.

It is surely reasonable to put in the spec that browsers SHOULD send a list
of ALL the MIME types accepted by their helpers.

My recollection is that the fisrt release of Netscape did this and then
it was suddenly replaced with the few types that could be displayed in-line
plus * for the rest.

It is exasperating not to be able to get the registered helper types from
the browser.
